371854 divided by 80 
The aim is to understand the frequency of 80 in 371854.

Advancing to step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 80

Step 2:
80 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 80

Moving on to step 3:
The number 80 fits into 371 4 times, leaving a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 320 from 371 leaves us with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 80

Step 4:
80 can be fit into 518 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 38 after subtracting 480 from 518.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 80

Moving on to step 5:
80 goes into 385 4 times with a remainder of 65.
Use 4 as the next digit of our solution. 
Result so far: 464.0
Subtracting 320 from 385 leaves us with 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 80

Let's proceed to step 6:
If we divide 654 by 80, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 4648.0
Deduct 640 from 654 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 80 fits into 140 1 times, leaving a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 4648.1
If we take 80 away from 140, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 4648.17
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4648.175
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4648.175
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4648.175
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4648.175 with a remainder of 0.0.
